Need some help with turn signal switch

Thanks for all the help (and picture) guys. I am kind of new here and didn't know how to search past forums to see if anything applied to my problem. Hopefully nobody here minded discussing it again.:)

So I basically need to replace the switch then? does anyone here know if the ebay part listed here will fit my car,or what part number I need for mine? and thanks for the warning about the Dorman aftermarket junk found in the autoparts stores. I want to do it right the first time.

How hard is is to replace this switch? ive replaced ignition locks before and have all the pullers and tools.
